Dennis_Churaev [7]

Answer:

The number of adult's ticket is 50.

The number of children's ticket is 20.

Step-by-step explanation:

Given that, seventy ticket were sold for $550.

Let the number of adult's ticket be x.

Then the number of children's tickets is = (70-x)

Each adult ticket cost $9.

Then the cost of x number of adult's ticket is = $9x

Each children's ticket cost $5

Then the cost of (17-x) number of children's ticket is=$5(70-x)

=$(350-5x)

According to the problem,

$9x+(350-5x)=550$

$\Rightarrow 4x+350=550$

$\Rightarrow 4x=550-350$

$\Rightarrow 4x=200$

$\Rightarrow x=\frac{200}{4}$

$\Rightarrow x=50$

The number of adult's ticket is 50.

The number of children's ticket is (70-50)=20
